Zeroscope 1U Manual
Note Name Display
The top line shows CH1, and the second
line shows CH2.
Zeroscope displays the note name closest
to the incoming pitch, plus a vertical line
indicating how far the pitch is from that
note (from -45 to +45 cents).
A note is sharp if the vertical line is to the
right of the note name. For example, in
this illustration the vertical line is to the right of the note name for CH2, indicating that
CH2 is playing a C3 (“middle C”), but that the note is sharp.
A note is flat if the vertical line is to the left of the note name.
A note is perfectly in tune if a box surrounds the note name. In this illustration, the box
around the note name for CH1 indicates that it’s playing a C1 note, and that it’s perfectly
in tune.
Reference Pitch and Averaging Time
Both the Hz Display and the Note Name Display have two additional options at the
bottom of the scope: ref and avg.
ref This displays the reference pitch used by the tuner (which displays the
number of Hz to which the A above middle-C is tuned). Most devices
default to 440Hz, but other standards are sometimes used.
avg This displays how long the Zeroscope spends averaging out frequency
variations before it recalculates and reports a new note name. There are
three options: slow; norm; and fast. Fast is very sensitive to fluctuations
on input, while slow is not. Norm is in the middle.
A small indicator arrow to the left of the ref or avg parameter indicates which will be
changed by rotating the encoder. To change whether the encoder edits ref or avg, switch
between Hz and Note Name displays. Specifically:
1. After entering Tune mode, wait five seconds for the little Tune mode indicator in
the upper right corner to extinguish.
2. With Hz display active, turn the encoder (without pushing it) to change the avg
setting (slow, normal, fast)
3. Switch to the Note Name display, and turn the encoder (without pushing it) to
change the ref tuning value.
